ATTORNEY To dll whom) it may concern:

Be it knownthat I, JoHN E. OHEARNE, a

citizen ofthe United States of America, residel ving at Norwallgin the county ofHuron and State'of Ohio, have invented vor discovered new and useful Improvementsin Trimmers,

of which the following is a specification. v My invention relates to trimmers forfilling cars, ships, and the like.

great #deal of material delivered by gravity into cars and vessels cannot, because of the rigid construction em loyed and the limiting area ofthe doors an hatchways, be distributedover the entire surface, but must be shoveled or otherwise distributed by men employed for that purpose, this method "ing uns;

being Anot only slow but-very expensive.

yReferring'to theidrawi'ngs, Figure 1 is 'a side elevation of myf'invention withparts broken laway Fig. 2,""a' plan of non-rotatable bearing ring,` Fig. 3,` a cross-section of the same; Fi 4,a plan of half the rotatablebearig. 5, anelevation of a half ofthe `latter ring; Fig.V 6, an enlarged elevation of the lower portion of Fig. 7, looking toward the right; and Fig. 7, aside elevation of my lso hatchway. y

My invention is shown attached to"` the chute of a car-dumper or coaling machine, eX-

invention in connection witha portion of a tensively used `alongthe Great Lakes for transferring coal from cars to vessels, but it is applicable to ore 'do.cks,fcoal docks, grain elevators, blast furnaces, ystock bins, etc., and to any purpose where gravity controlled distribution is desired.

On the drawings, 1 is a chute which may be of any desired form, its upper end leading to. any source of supply of material to be fed by gravity through said chute into a vessel or other receptacle. The lower end of the chute 1 is supplied with a ring 2, having preferably the circular ball-'bearing surface 3, in which the groove 4 forms a race for the anti-friction ballsA 5. It is to be understood that any'other form of anti-friction devices,

i" such as rollers, cones, or the like, may be emhas the groove 7 vregistering with the groove 4v plo ed, or that such devices may be entirely omltted, if desired.

Coperating with1 the ring 2 lsrotatable ring 6, which is supported by the r1ng2 and to form a completely lclosed race for the balls 5. The ring 6 has pendent therefrom, the

spout or chute 8 havin the straight portion.

' Patented-Mayes, 190s;

In thechute is 'a deflectingplate or. valve 11, mounted rigidly on .the rock-shaft 12 so as to form a contlnuation of the. straight side-of the chutet and then prevent lany:v material from passingalong the deiiecting portion'jofthe chute, or to take an-inclined'position across the chute so as to form a-te'mporary bottom therefor and deilect the material into the said 12 is provided witha handle 13,-'havling a catch 14 which locks inanotch at either end n t of the section A 15. ,When the handle is thrown so that the catch -is inone notch,` the valve or plate 1 1 will close the deilectingportion ofv t elapihute, and when the handle is thrown inft catch locks in the other notch, thesaid valve will ,detlet the material into` the inclined :por-

It will benoted on Figs.` 4 5, that the ring '16 is made u of distinctlateral,sections which are secure together bythe rivets 6', l

shown in Fig. 6 as extending through the tritions 6 can be assembled with the section2 by moving the lateral sections into place ywith the grooves 4 and7 registering.` ,f

On the top of the ring' 's the circular rack 16, meshing with the .p1ni`on"17, carried on the shaft 18Which is driven by the pulley 19 l thereon from any suitable source ofpower. The shaft 18 is carried in bearings onthe ries the hoisting pulleys 20 by which the chute 1 with the pendent parts may be raised and lowered.

On Fig. 7, 21 shows the roof of a compartment in a vessel, 22 being a hatchway o ening thereunto. If the straight spout 9 a one Vbe used, the material would be deposited in the form of a frustumof a cone, as indicatedbythe lines 23, which lines would, even when the lower end of the spout is just at the open-` ing 22, leave a large portion of the com artment unfilled between 4the material an( the In such a case, the filling of the compartment ceases and men must be employed' to shovel the material away. The 105 chargin and shoveling operations follow each ot er until thecompartment is filled. With my invention, when the coneindicated by the lines 23 is formed, I swing the lever 13 from its upper to its lower position, thereb 110 moving the valve or plate 11 from the fu liney to'the dotted line position shown on Fig. y

e opposite directionuntil its 1, whereu` laterally t o`-gh the chute or spout 10. At

the same time pulley 19 is set in motion,

whereby the material isl distributed evenly aroundv the compartmentand at a very much higher position than it was deposited by the chute or spout 9. By making the rotation rapid, centrifugal force would enter into the action of the spout 10 and the material could be thrown to form almosta horizontal surface close under the roof 21, the whole apparatus being raised-b the pulleys 20, as desired to raise the leve of the"distribution.
